After repeated cross-tagging, e.g. in the CatNr range 68993 to 69003, the GP data for these objects now seems to remain stable.
Gemini-Pollux CatNr now remains 69000.

Three unidentified satellites from the Kosmos 2600 launch (2026-023) illegally transmit 62.5 kHz wide LoRa signals on these UHF frequencies:
obj 67679 (2026-023F) on 430.772 MHz,
obj 67680 (2026-023G) on 430.912 MHz and
obj 67682 (2026-023J) on 430.632 MHz.
Doppler measurements show that OrigamiSat 2 is object 68795 (2026-088D).
Frequency: 437.506 MHz.

Apparently 18thSDS has some issues with determining the correct GP data of several objects, e.g. 68998 to 69003. The GP data shows large jumps over time. Therefore the data for Gemini-Pollux, likely CatNr 69000, is not valid most of the time.
